About this item
  • High-transparency glass: This co2 drop checker excellent light transmittance, ensuring clear visibility throughout the monitoring process without the need for repeated disassembly. Equipped with an upgraded, reinforced suction cup, it has strong adhesion, firmly adhering to the aquarium wall and preventing it from shifting during water changes or feeding. Suitable for freshwater aquariums of all sizes, it's easy for beginners to install
  • Complete Set: The co2 aquarium kit includes a 15ml high-sensitivity indicator and a high-transparency glass monitoring tube. No additional accessories are needed; it's ready to use right out of the box. It accurately monitors and controls CO₂ concentration in freshwater aquariums, preventing imbalances and providing ample oxygen for fish and shrimp, as well as suitable photosynthetic conditions for aquatic plants. This creates a stable and healthy aquarium environment, making it an essential tool for every fish enthusiast's aquarium maintenance
  • Intuitive Monitoring: The aquarium co2 kit uses three clear color differences to visually represent CO₂ concentration, eliminating the need for professional instruments: yellow indicates excessive concentration, which can cause fish and shrimp to suffocate due to lack of oxygen; green indicates an appropriate concentration, balancing the safety of fish and shrimp with the photosynthesis of aquatic plants; blue indicates insufficient concentration, which can cause yellowing leaves and stunted growth in aquatic plants. A single glance allows for precise control
  • Beginner-Friendly: The high-contrast color-coded design allows for precise adjustment of the CO₂ system without requiring professional fishkeeping knowledge or complex operations. It effectively avoids problems such as mass mortality of fish and shrimp and withering and yellowing of aquatic plants caused by CO₂ imbalance. Even beginners can easily set up a vibrant and stable aquarium
  • Easy Operation: The operation process is extremely simple, requiring no professional skills. Simply pour the test solution into the monitor base; connect the pre-installed suction cup to the test tube; and attach it to the aquarium wall to complete the installation. Observe the color change of the test solution in real time through the high-transparency glass tube to easily determine whether the CO₂ concentration is increasing, decreasing, or remaining stable. Daily monitoring requires minimal additional time
